IMPROVEMENT IN IRON RAILWAY CHAIRS AND CROSS-TIES.

Specification forming part of Letters Patent No. 46,541, dated November3, 1863,

To all whom it may concern:

I Be itknown that l, Looms G. MARsHALL, of the city of- Philadelphia andState of Pennsylvania, have invented new and useful Improvements in Ironand Steel Railway Chairs and Cross-Ties and I do hereby declare thatthefollowing is a full and exact description thereof, reference beingbad to the accompanying drawings, and to the letters of reference markedthereon, making a part of this specification. I

The nature of my invention is an improved railway-chair, made of steelor iron, and its arrangement and combination with a tie and key.

To enable others skilled in the art to make and use my invention, I willproceed to de scribe its construction, as. follows:

Figure 1 represents a View of the railway; Fig. 2, an end view, and-Fig.3 a view, of the chair.

A represents the ordinary T-rail, reversed, top down, the wide partlthebase or flanged sides 13) resting in the chair 6, underneath, andfitting into the top groove of the chair, which is square-shaped, andhas .two similar grooves-one at top, lengthwise, and the other atbottom, crosswise. The rail slides into the top groove, and thecross-tie slides into and fits in the lower groove. The cross-tie D,being shaped like the lower part of the railA, having a flange at eachside that the sides of the groove of the chair 0 clasp and bind firmly.

On the outside. of rail A and on one side of tie D, between the rail andchair and between the tie and chair, a wedge-shaped key, E, is driven,which key is stayed by apin driven through its narrow end. The chairthus holds the rail and tie firmly and securely.

Between the rail and the chair and between the chair and the tie I havean elastic or guttapercha cloth, G. These pieces of rubber lining G giveeaseto the cars and 'prevent the tie and rail from breaking, renderingthem free from sudden jars, and relieving them from the strain producedby the engine and making the roadvmore durable. The whole is intendedfor easy and quick transportation and facilitating the building ofrailways at the cheapest cost'possible.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The square-shaped double-grooved chair with its elastic rubbers, asherein described.

2. The arrangement and combination of the rail-chair and tie, arranged,constructed, and keyed together as herein described, and for thepurposes set forth.
